Hi John,

Thanks for sharing your experience. Would you mind sharing your thought on
why this was the case? Do you think it was because C18 needs more
improvement to better take advantage of the extended instructions or was it
because your application did not lend itself very well to the extended
instructions? I'm just curious and would like to get your take on this.
You've written some great stuff on C compilers on your web site and I value
your opinion.

Thanks again John. I appreciate your time.

Best regards,

Ken Pergola
